Product Overview
Directly addressing continuous operating cost scaling and absolute system protection, the Grundfos SEG.50.31.EX.2.50B delivers exceptional commercial consistency. Grundfos SEG pumps are specifically designed for pressurized pumping of wastewater with discharge from toilets. This technological solution decreases power consumption while improving fluid evacuation speeds.
Centered deep within the casing resides a dedicated grinder system explicitly configured to destruct volatile solids into highly manageable tiny pieces, successfully enabling frictionless transit through restricted piping structures. The outer casting surface is purposefully crafted to be entirely smooth, limiting the ability of organic dirt to physically adhere.
Producing a remarkably reliable 3.1 kW of pure rotational mechanical output, this submersible solution provides incredibly consistent internal hydraulic pressure. Calibrated explicitly for three-phase 415v electrical grids, the pump sustains a formidable maximum head of 23.8 meters while processing a continuous maximum flow of 516 L/Min effortlessly.
Developed with operational safety as a fundamental priority, this pumping solution is equipped with a heavily insulated electrical harness. The specialized power cable incorporates dedicated wires for thermal sensors buried deeply within the main motor winding. This strict arrangement constantly guards against internal temperature spikes.
Features
- Pulls exactly 7 Amps of maximum continuous rated current during highly aggressive deep trench organic grinding cycles.
- Built with a highly expanded 50 millimeter nominal diameter DIN oriented internal outlet port pipe configuration.
- Includes a distinctly rugged ten meter external power cable seamlessly ensuring highly versatile underground deployment depths.
- Certified fully compliant under extremely rigorous ATEX II 2 G Ex db IIB T4/T3 Gb hazardous environment explosion proofing standards.
- Operates smoothly at an internal rated operational speed of 2900 rpm for absolutely maximizing incoming biological solid shearing.
- Delivers highly impressive eighty-four percent internal motor efficiency while fully submerged under maximum physical liquid strain.
